CLOCK_PERIOD update

- Updating the clock period of all designs in hd to reduce the spef_wns by adjusting the CLOCK_PERIOD to the value of the suggested_clock_period of a previous regression run. - Some designs were left with clock periods that produce a negative spef_wns to be used as a test of the functionality of the timing closure tools (OpenSTA, OpenPhySyn, and SPEF_EXTRACTOR)
